Caspar Schlickum

Caspar Schlickum is best known for his leadership of Xandr, AT&T's advertising and analytics company, where he served as CEO and helped position the platform at the intersection of premium video, data-driven advertising, and programmatic infrastructure. Under his tenure, Xandr worked to differentiate itself through its Invest DSP and Monetize SSP products, as well as its ambitions in addressable TV advertising — areas that placed it at the forefront of the industry's shift toward converged TV and digital buying. Before his role at Xandr, Schlickum built a strong foundation in the programmatic and data-driven advertising space through his work at WPP's programmatic unit. He served as CEO of Wunderman Data Products and held senior roles within the WPP ecosystem, giving him a deep understanding of both the agency and technology sides of the advertising industry. His career reflects a consistent focus on the infrastructure and data layers that underpin modern advertising. Schlickum is regarded as a thoughtful operator in the AdTech space, known for navigating complex organizational environments — including Xandr's eventual acquisition by Microsoft in 2022 — and for articulating a clear vision around the role of identity, data, and premium inventory in the future of programmatic advertising. His experience spans both the buy and sell sides of the ecosystem, making him a well-rounded voice on platform strategy and industry evolution.
